which is employedfor the reduction of speed as the occaslon may require.

At the front endof the machine the frame 10 is braced by members 16arranged in di:

vergent relation and adjacent the transverse` he main frame, asillustrated. The members 16 are connected with a bolt 17 end member of t10, and designed to straddleand repose upon' .the front axle 18.

The rear end of the frame 10 is braced by a transverse member 21 uponwhich the frame Y 10y reposes, the member 21 being connected with thespring perches 22 in lace 'of the usual transverse spring, and arc ed abat 23 to ass over the differential.

arried byand suspended from the main frame of the machine is anauxiliary -frame clearly shown in Figures 1 and 2, and which auxiliaryframe is rectangular in plan and of a size to project an appreciabledistance be ond both sides of the machine, as shown.

is auxiliary frame includes a front bar 24 arranged in advance of thefront wheels of the machine and transversely thereof and which bar isbraced and supported by diagonally spaced bracing members 25 which havef their corresponding rear extremities suitably lsecured to t theirforward extremities are secured to the front bar 24 at the ends thereof.

This front bar is further supported and braced byspaced parallel bracingmembers 26 which are suitably arched as shown in Figure 3 to pass overthe front axle, the corresponding 'rear extremities of these mem bersbeing securedto the rear or adjacent bar 27 of the auxiliary members'28of the frame, which have their' forward extremities pivotally connectedframe,.while their correspending forward extremities are pivotallyconnected with the front har 24. These e sides of the main frame, whileesv nis

with the front bar24. Again, the front bar v24: of the frameis bracedand supported by spaced-.members29 which are'of angular con and haveworking clearance with the bar 27 7, land act by contact with themembers 26 to vprevent lateral movements 'of thebar 27,

While still permitting it to rise an'd fall. When the braces 19 are usedthey act to assist the guide bars 26 in this function, though,

due to their considerable distance from theA bar 27 and the flexibilitythus introduced,

this is of slight importance. The braces19 are used, however, only undersome conditions, and for the purpose of preventing tools which tend todig into the ground, from rocking the machine when used in hard ground.But, as they prevent pivotal action of the frame on the front axle theyare never used when this can be avoided.

This construction and arrangement of parts not only supports theauxiliary frame upon the main frame of the machine, but allows theauxiliary frame to be raised or lowered with relation to the ground toproperly position the cultivator tools for the work to be accomplished,and also allows the auxiliary frame to be tilted endwise when the may/chine is moving over inclined or hilly teritory. f

The rear bar 27 includes spaced upper and lower sections, as clearlyshown in Figure 1, and between these sections are passed bolts 30 whichare utilized to hold the cooperating parts 31 and 32, respectively, of aclamp associated with said bar, these Clam s being used in conjunctionwith the shans 33 of the cultivator tools indicated at 34.

The shank 33 of each tool is provided with slots 34 so'that the saidtools are susceptible of vertical adjustment with relation to theadjacent bar 27 of the auxiliary frame, and also susceptible of tiltingadjustment by reason of the slot and pin connection, indicated at 35.

In addition to these ailjustments of the cultivating tools the lattermay be also slid along the bar 27 so as to space the tools any desireddistance apart, and to accomplish this it is only necessary to loosenthe bolts 30 to slide the latter between the sections of the transversebar 27, as will be readily understood.

For the purpose of adjusting the auxiliary frame, I employ a shaft 36journaled transversely of the frame 10 and having crank arms 37 and 38at the ends thereof. 'The crank arm 37 is pivotally connected with theadjacent end of a link 39, While the lower end of this link is pivotallyconnected with a link 40 associated with the adjacent arch-shaped uidebars 26 are securelyy attachedto-the rameilvO (see'Figures 1, 2, 3 and8) bracing member 26, as clearly shown in Figure The other crank arm 38is also connected with the adjacent arch-shaped bracing member 26, butindirectl. so through a construction vof means to be presentlydescribed, which allows the frame in its entirety to be raised andloweredl with relation to the ground incident to the operation of thelever 41, and independently operated by meansof a lever 42, when it isdesired to only raise one end of the frame. This connecting meansincludes a frame 43 which is pivotally connectedv as at '44With, thecrank arm 38. Pivotally mounted on this frame 43, as at 45, is the lever42 above referred to, thel lever 4l being carried by the shaft 36.

A link 46 is pivotally connected with the lever 42 adjacent its lowerend, and rovides a connection between this lever an the adjacentarch-shaped bracing member 26 of the auxiliary frame.

The frame 43 is provided with a rack bar 47 with which a pawl 4Scooperates to hold the lever 42 in a given position. The frame 43 isalso formed with a sleeve 49 which slidably receives a guide rod 50, thelower end of the latter being connected with the same link 51 thatprovides a connection between the link 46 and the adjacent bracing mem-,ber 26.

It isdby reason of this construction and arrangement of the rod 50 thatthe connectingr meansbetween the crank arm 38 and the auxiliary frame isafforded the proper rigidity to maintain the parts in working relationincident t0 the operation of either of the levers 41 and 42, resectively.

When it is desired) to raise and lower the auxiliary frame in itsentirety from the front bar 24, the lever 41 is-utilized, and when thislever is operated the frame 43 and its associated parts all move as aunit under the in- `iiuenc'e of the lever 41. However, when it isdesired to raise or lower one end of the auX- iliary frame independentlyof the other end thereof, the lever 42 is employed, which allows theframe 43 to be swung upon its pivotal connection 44 to so adjust theauxiliary frame independently of the lever 41, as will be readilyunderstood. The levers 41 and 42 are arranged within convenient reach ofthe operator and can be very easily manipulated for the purposesintended.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown `anddescribed, and that such changes may be resorted to when desired as fallWithin the scope of what is claimed.
